DNA comparisons of the two orthopoxviruses monkeypox and variola
… smallpox has been eradicated there are animal poxviruses which are closely related. It is desirable to measure the closeness of this relation to assess whether Variola virus could re-emerge as a complex mutant of an animal poxvirus. The most likely candidate is Monkeypox, which can produce human …

Molecular and evolutionary analysis of a gene conserved in most Orthopoxviruses
Evidence is presented to show that variola and monkeypox viruses evolved independently from a common ancestor. An open reading frame (ORF), potentially coding for a protein of 341 amino acid residues, was found to be conserved in two strains of variola virus (Harvey and Somalia), but degenerate in …

Virus discovery using current and novel methods
… samples, and ancient remains. The recovery of viruses from such datasets can provide insights into the diversity and evolution of both novel and already known viruses. This thesis focuses on two aspects of virus discovery in NGS datasets. In the first part of this thesis, I present ancient …

Characterization of the anti-viral effects inhibited by the vaccinia virus K1 protein
Vaccinia virus (VV), a member of the poxvirus family of double-stranded DNA viruses, is well-known as a highly effective vaccine against variola virus, the causative agent of smallpox. Poxviruses encode many strategies to evade the host immune and anti-viral response. One such host anti-viral …

TRIM5α is a poxvirus restriction factor: viral evasion strategies and a pathway to antivirals
… TRIM5α as a restriction factor for vaccinia virus (VACV) and two VACV countermeasures. This study followed up a proteomic analysis showing that VACV infection of TERT-immortalised human foetal foreskin fibroblasts (HFFF-TERTs) induced TRIM5 downregulation. This observation was validated in …
